My dealer uses Venture Shield. 3M makes several grades of protective film, two called Aerogard and on called Clear Mask. I am not sure what, if any difference there is between the 3M products and Venture Shield. Also I am not sure that there are not other brands that may be better. BWM's accessory catalogue for the 6 also has clear protective covering. If anyone has links to comparisons or experience with clear covering material I would appreciate your feedback. I would like a film installed before delivery, which I expect next week, or as near to it as possible.
